CONVEYING APPARATUS.

SPECIFICATION forming' part of Letters Patent NO. 580,415, dated April 13, 1897. Application filed December 17,1895. Serial No. 572,402. (No model.)

T0 a/ZZ wiz/071e L'Z'; may concern:

Be it known that I, THOMAS SPENCER MIL- LER, a citizen of the United States, and a resident of South Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in' Conveying Apparatus, of which the following is a speciiication.

My invention relates to improvements in hoisting` and conveying apparatus of the kind in which the actuating-motor is carried by the load-carriage.

One of the advantages that may be derived from my invention is location of the hoistwheel or hoist actuator above the track. Other advantages and features will be apparent from the following description.

In the accompanying drawings, Figure l is a side View of the apparatus. Fig. 2 is a plan view. Fig. 3 is an end view. Fig. 4 is a detail.

a a are the tracks.

Z3 b are the wheels Xed to axle c.

b2 b3 are the wheels xed to axle c.

CZ (Z are the side plates or frames of the car, of the form shown, suspended from the axles. e is the bottom frame or plate of the car.

fis the seat for the operator, fixed to the car.

g is an electric motor on the car.

ZL is the shaft driven by the motor.

ZL h2 are gears between the shafts Z1l and i.

Z and m are sprocketwheels free to revolve on the shaft t. They are respectively thrown into and out of engagement With the shaft by the hand-levers Z2 and m2, each operating a clutch mechanism similar to that shown in Fig. 4. Clutch member m3 is fast to the sprocket-wheel. Cooperating clutch member m4 is splined to shaft t. Lever m2 is free to turn on the shaft, but carries on one side a screw-thread m5, engaging with a screwthread m6, fast to the frame. On the other side it carries a fork m7, engaging with a groove in clutch member m4.

m8 is a collar iixed to the shaft t'.

fn, is a sprocket-wheel fixed to axle c'.

o is a sprocket -wheel fixed to shaft 0'.

Sprocket-chain Z connects sprocket-wheels Z and o. Sprocket-chain m connects sprocketwheels m and n. A shaft p is geared to the shaft 0 by the gears p p2.

q is the hoist-line, which may be a rope or chain, though preferably a chain.

q is the load.

fr is a wheel or sheave fixed to shaft p above the track over which the hoist-chain passes and which engages the chain in such manner as to compel it to move as the wheel moves.

s is a receptacle for the loose end of the chain, which receptacle is fixed to the frame of the carriage by the connection S2.

s is a weight attached to the end of theV chain.

The operator by the movement ofthe clutchlevers causes the motor to operate either the hoist-wheel r or the traction-wheel b3. Thus the operator causes the motor to hoist the load to the point desired and then causes the car to travel along the track to the point desired.

By placing the hoist-wheel above the track much economy of space is secured, the weight can be hoisted up as high as the track itself, and the motor and operator can be placed close up to the track, as shown in Fig. l.

I claim- In a hoisting and conveying apparatus, in combination, a track, a carriage running thereon and extending below the level of the track, a motor mounted on the carriage below the level of the track, a support for the operator also mounted upon said carriage below the level of the track, a hoist-line actuator mounted on said carriage above the level of the track, a hoist-line passing over said hoistline actuator and hanging below the level of the track at both ends and means whereby said hoist-line actuator is driven by said motor, substantially as described.

THOS. SPENCER MILLER.
